Automatic Cylindrical Battery Sealing Machine Cases Crimping Machine
1. Equipment Function and Principle
l This linear-type sealing equipment is mainly used for crimp sealing cylindrical battery steel shells after electrolyte injection and cap assembly. It features safe and reliable operation, stable performance, and convenient operation.
l The cells are conveyed in a straight line for loading and unloading. The motor drives the crankshaft to pull down the first, second, and third sealing dies, as well as the crimping die, to sequentially perform the sealing of the cell steel shells.
2. Equipment Operation Process
l The operator uses a magnetic cell holder to pick up a full row of cells and place them onto the infeed belt. The belt conveys the cells to the infeed pushing station. When the sensor detects the cells, the pusher cylinder pushes the cells to the sealing station.
l The upper die descends, and simultaneously, the lower die base automatically closes to position the cell (the lower die closure is achieved by the upper plate pushing down the closing guide rod, causing the wedge block to close the lower die base).
l While the lower die is closing for sealing, the next cell is fed in. The pusher block retracts, awaiting the next cell to enter the sealing die. After crimping, the upper plate ascends, the lower die base opens, and the cycle continues. There are four sealing stations in total: first sealing, second sealing, third sealing, and crimping. The cell must pass through all stations to complete sealing.
l Operation sequence: Manual loading to infeed belt → Infeed belt delivers cells to sealing station → Pusher cylinder pushes cells one by one → Die closing, three-step sealing → Crimping → Cylinder pushes cells to discharge chute → Manual collection using magnetic holder.
